Description

[Detailed Description of the Invention] The present invention relates to a lattice for balconies, handrails, etc., and particularly to a new lattice assembly structure that can be easily assembled without welding.

Traditionally, grid assembly was mostly done by welding or bolting.

When welding is used, it is difficult to completely paint the welded areas, which causes rust to occur in these areas.

In addition, in the case of bolt tightening, it is very time consuming to tighten each bolt one by one on site and assemble.

The present invention improves the deficiencies and strengths of the above-mentioned known techniques, is easy to assemble, and can be provided at low cost, and will be described below with reference to the drawings.

FIG. 1 shows a lattice assembled using the assembly structure according to the present invention, where 1 is a baluster, 3 is an upper rail of the lattice, and 4 is a lower rail.

The present invention is used for assembling the baluster 1 and the upper and lower rails.

Referring to FIG. 2, elongated holes 5, 5 are bored diametrically opposite each other at a position slightly below the upper end 8 of the baluster 1.

Reference numeral 2 denotes a stopper for assembly, which is U-shaped and integrally provided with protrusions 6, 6 having downward slopes 6a on both sides.

FIG. 3 shows a state in which the stopper 2 is fitted into the upper end of the baluster 1. To fit the stopper 2, the U-shaped stopper is pinched with fingers and pushed into the baluster 1.

At this time, when the protrusion 6 and the elongated hole 5 of the baluster are aligned and pushed in, the protrusion 6 protrudes as shown in FIG. 3, and the preparation for assembling the baluster 1 with the upper beam 3 is completed.

Now, the baluster 1 assembled as shown in FIG. 3 is assembled with the upper rail 3 in the following manner.

A through hole 7 with a diameter slightly larger than that of the baluster is pre-drilled in the upper crosspiece 3 in accordance with the required spacing between the balusters 1, and when the top part 8 of the baluster 1 is inserted into this through hole 7, the baluster is initially 1 enters smoothly, but there is resistance when the protrusion 6 hits the edge of the through hole 7, so if you push it hard, it will enter along the slope 6a of the protrusion 6.

Of course, the projection 6 is pushed into the baluster against the spring force of the stopper 2.

The design is such that when the top 8 of the baluster 1 hits the inner wall surface 9 of the upper crosspiece 3, the protrusion 6 also exceeds the through hole 7.
As shown in FIG. 5, the protrusion 6 projects laterally again and connects the baluster 1 and the upper rail 3.

Although the above description has been made regarding the case where the baluster 1 is assembled to the upper rail 3, the relationship between the baluster 1 and the lower rail 4 can be similarly assembled as shown in the lower side of FIG. 5.

FIG. 6 shows another embodiment of the stopper, this example being formed by a press or a form.

The stopper 10 is U-shaped like the stopper 2, and has a protrusion 11 with inclined surfaces 11a on both sides.

Since the present invention is constructed as described above, it has the following advantages over conventional assembly methods.

1 It is easy to assemble and the parts can be transported to the site, making packaging and transportation cheaper.

2. If parts are painted in advance, painting costs can be significantly reduced compared to painting after assembly.

3. Since pre-painted members can be used, the colors of the upper and lower rails, balusters, etc. can be varied.

4. Since no welding is used, combinations of several materials are possible.

5. Since there are no welded parts, there are no problems with rust occurring from these parts.

6. Since the cut and processed parts do not appear on the surface, a grid with excellent appearance can be obtained.

4''''l The above is the connection structure between the baluster and the upper or lower rail (No. 7).
Although the explanation has been made regarding FIG. A), if the present invention is applied to the section seen by arrow B in FIG. 7, it is possible to obtain a surface grid in which no bolts are exposed on the entire surface.
